U.S. Senate panel OKs asbestos subpoena power

So now the defendant companies will testify in front of the Judiciary Committee. Say hello to Judge Roberts on the way in.

I wonder if the companies can invoke some sort of attorney-client privilege? Or, if they happen to be public, point to their SEC filings? Of course, they could just say they really don't know and declare bankruptcy. That would sure throw a wrench in the works.
